I'm very proud of this cosplay, since it's the first I made entirely myself, without buying anything (well, except for the material) It's still very amateurish, and I have seen some Celestias that were waaay better than mine (but also some that were crappier...). But I like it very much, anyways!

no worries! Thanks anyways for the reply :-3 I ended up hot gluing bobby pins to the bottom of the ears (3 of em) and some to the horn (just two) and it was perfect! I was using cloud clay so I'm not sure drilling would have worked out very well ><
